I would prefer to use "distance" instead of "length".distance = speed x time
enough
Probably that refers to expressing length in standard (metric) units, like meters, millimeters, and kilometers, instead of some non-standard (non-metric) unit like feet, or light-years.
This is because a number represented in hexadecimal requires fewer digits. A hexadecimal string of length s can hold a number which is approx 8^s as large as a binary string of the same length.
Rhombus are like squares with 4 equal sides. However, it has no right angles unlike right angled. Instead, the opposite angles are equal.
The red (port) and green (starboard) are running lights and can tell you which direction the boat is heading in low visibility conditions. Remember the phrase, "red right returning," which means if the red light is on the right, the boat is returning, or headed towards you. The white light can be a masthead light or a sternlight, and its requirements vary depending on boat length and whether you're operating under international or inland rules.

You give no options but the standard lights depend on things like length overall. A minimum would be port and starboard running lights, masthead light and stern light
Lighting requirements vary depending on whether you're talking about a sailboat or powerboat, International Rules or Inland Rules, the length of the vessel, and whether or not the vessel is at anchor. However, if at night you see a single white light only (no red or green lights), you're most likely looking at a boat at anchor.
Generally they are masthead light, port and starboard steaming light and stern light. Others may be displayed depending on the length of the vessel and what duties it is carrying out.
Port (red) and Starboard (green) running lights and a white light which will be mounted on either the stern or the masthead.
Rule 21 of the Navigational Rules of the Road. (a) "Masthead light" Means a white light placed over the fore and aft center-line of the vessel showing an unbroken light over an arc of the horizon of 225 degrees and so fixed to show the light from right ahead to 22.5 degrees abaft of the beam on either side of the vessel, except that on a vessel of less than 12 meters (39'4") in length the masthead light shall be placed as nearly as practical to the fore and aft center-line of the vessel.
Killer whales are not measured in height. Instead, they are measured by length. The length of a orca is usually around 33 feet.

The metric system is not exactly equivalent to any other system, but there are units of measurement for anything that you may wish to measure. If you are accustomed to weighing things in pounds, you have the option of weighing them in kilograms instead. If you are accustomed to measuring length in feet, you have the option of measuring length in meters instead. You may be used to degrees Fahrenheit but you can use degrees Celsius instead.
If you are moving......green to starboard (right) red to port (left) white to aft (rear).If you are anchored......white all around.Rule 26Fishing Vessels(a) A vessel engaged in fishing, whether underway or at anchor, shall exhibit only the lights and shapes prescribed by this rule.(b) A vessel when engaged in trawling, by which is meant the dragging through the water of a dredge net or other apparatus used as a fishing appliance, shall exhibit;(i) two all-round lights in a vertical line, the upper being green and the lower white, or a shape consisting of two cones with their apexes together in a vertical line one above the other; a vessel of less than 20 meters in length may instead of this shape exhibit a basket;(ii) a masthead light abaft of and higher than the all-round green light; a vessel of less than 50 meters in length shall not be obliged to exhibit such a light but may do so;(iii) when making way through the water, in addition to the lights prescribed in this paragraph, sidelights and a sternlight.(c) A vessel engaged in fishing, other than trawling, shall exhibit:(i) two all-round lights in a vertical line, the upper being red and the lower white, or a shape consisting of two cones with their apexes together in a vertical line one above the other; a vessel of less than 20 meters in length may instead of this shape exhibit a basket;(ii)when there is outlying gear extending more than 150 meters horizontally from the vessel, an all-round white light or a cone apex upwards in the direction of the gear.(iii) when making way through the water, in addition to the lights prescribed in this paragraph, sidelights and a sternlight.(d) A vessel engaged in fishing in close proximity to other vessels engaged in fishing may exhibit the additional signals described in Annex II to these Regulations.(e) A vessel when not engaged in fishing shall not exhibit the lights or shapes prescribed in this Rule, but only those prescribed for a vessel of her length.
